At a difficult combination of 12 mm focal length and f/3.5 aperture the vignetting is distinct, reaching 46% (−1.78 EV). Taking into account the size of the sensor it is a weak result, noticeably weaker than that of the Olympus 12-50 mm. When you stop down the aperture to f/4.0 the vignetting decreases to 41% (−1.53 EV). A moderate level can be reached by f/5.6 where that aberration is 29% (−1.01 EV). By f/8.0 and f/11.0 the vignetting gets to respectively: 24% (−0.79 EV) and 22% (−0.73 EV).

At longer focal lengths the situation becomes noticeably better. At 20 mm and f/4.1 the vignetting amounts to 37% (−1.32 EV) and by f/5.6 it decreases to 31% (−1.08 EV). By f/8.0 and f/11.0 the level of that aberration is respectively 24% (−0.80 EV) and 20% (−0.66 EV).
In the case of the maximum relative aperture the brightness loss in the corners at 30 mm reaches only 22% (−0.72 EV). On slight stopping down to f/5.6 that aberration decreases to 21% (−0.68 EV). By f/8 and f/11 the vignetting becomes almost imperceptible, amounting to 12–13%.
At 60 mm and by f/5.6 you have to take into account the loss of 29% (−0.99 EV) of light in the corners. The aberration becomes slight by f/8 where it reaches 13% (−0.41 EV) and disappears practically completely by f/11 (8% and −0.25 EV).
RAW files differ from JPEGs only at the shortest focal length where the image after distortion correction is noticeably cropped. That’s why the vignetting reaches as high as 59% (−2.62 EV) for RAWs at the maximum relative aperture. By f/4.0 it still remains huge, getting to 56% (−2.42 EV). Also by f/5.6 and f/8.0 you deal with huge losses of light, with vignetting levels of 45% (−1.73 EV) and 35% (−1.24 EV). Even by f/11.0 the vignetting can be noticed as it still reaches 27% (−0.90 EV).
